Introduction: Emicizumab prophylaxis is approved for people of all ages with haemophilia A (HA) including infants and children. Although previous studies have demonstrated the efficacy and tolerability of emicizumab in infants with HA, real-world data on emicizumab use in infants are limited. The Haemophilia A in Infancy and NewbOrns: multi-instituional prospective observational study to assess the efficacy anD safety of Emicizumab (HINODE) study aims to evaluate the coagulation potential and safety of emicizumab prophylaxis in infants with congenital HA from birth to <12 months of age.

Importance: Emicizumab (EMI) is efficacious and safe for hemophilia A (HA) prophylaxis. However, its high cost poses a challenge in China.
Objective: To explore the possibility of using reduced-dosage EMI in Chinese HA children.

Hemophilia A (HA) patients under emicizumab prophylaxis may require the concomitant use of procoagulant factors for breakthrough bleedings or immune tolerance induction (ITI). The aim of this study is to evaluate the ex vivo procoagulant effect of plasma-derived FVIII concentrates containing von Willebrand factor (pdFVIII/VWF) in samples from patients with severe HA without inhibitors on emicizumab prophylaxis. Samples from healthy controls (HC) and HA patients were drawn in sodium citrate plus corn trypsin inhibitor tubes and spiked with increasing concentrations of pdFVIII/VWF concentrates (10-400 IU/dL) (Fanhdi/Alphanate, Grifols), activated prothrombin complex concentrate (aPCC, 0.

Patients with hemophilia A and B who have inhibitors face limited treatment options, because replacement therapy with clotting factor VIII or IX concentrates is ineffective, particularly for patients with high-titer inhibitors. Current mainstay therapies include immune tolerance induction (through frequent injections of clotting factor VIII or IX concentrates) to eradicate inhibitors and bypassing agents (such as recombinant activated clotting factor VII and activated prothrombin complex concentrates) for the prevention and treatment of bleeding episodes. The use of these agents typically requires intravenous injections and sometimes hospitalization, which can be burdensome for patients.

Aims: Haemophilia is a rare genetic disease that hinders blood clotting. We aimed to review model-based cost-effectiveness analyses (CEAs) of haemophilia treatments, describe the sources of clinical evidence used by these CEAs, summarize the reported cost-effectiveness of different treatment strategies, and assess the quality and risk of bias.
Methods: We conducted a systematic literature review of model-based CEAs of haemophilia treatments by searching databases, the Tufts Medical Center CEA registry, and grey literature.
